MACHINE FOR PUTTING UP PACKAGES.

SPECIFICATION forming part of Letters Patent No. 494,688, dated April 4,1893. Application filed September 24, 1891. Serial No. 406,709- (Nomodel.)

To all whom it may concern:

Be it known that I, EDWIN B. OLMSTED, of Yorkshire Centre, in the countyof Oattaraugus and State of New York, have invented a certain new anduseful Improvement in Machines for Putting Up Packages; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the drawings accompanying thisspecification.

My invention relates to machines for wrapping and packing dry material,such as tobacco, starch, and the like substances, wherein paper or otherflexible material is first formed into open top wrappers of apredetermined size and then filled with the material and the top foldedand pasted down thereon, the whole operation of forming the wrappers,fill ing the same, and folding their tops and delivering the completedpackage from the machine being performed by the one machine, and theinvention consists of the parts and combinations of parts hereinafterfully described and claimed.

In the accompanying drawings forming a part of this specification,Figure 1 is a plan View of my improved machine, a part of the frame workbeing broken away to show underlying parts; Fig. 2 a side elevation ofthe same, with the frame partlybroken away; Fig. 3 an enlarged detailplan view of the devices for folding the end flaps of the body of thewrapper and making the bottom folds and the co operating parts, showingthe jaws closed; Fig.4 a similar view showing the jaws open; Fig. 5 anenlarged detail perspective view of the device for operating theswinging folding plates; Fig. 6, a detail view, showing the device formaking one of the bottom folds; Fig. 7 a vertical longitudinal sectionthrough the pasting device; Fig. 8 a detailview, partly in sideelevation and partly in section, showing the means for discharging thepackage from the machine; Fig. 9 avertical section of the fillingdevice; Fig. 10 a detail plan view of the plates for the end of thefeeding tube; Fig. 11 an enlarged detail perspective view of a portionof the jawsl I; Fig. 12 an enlarged detail view, in side elevation, of aportion of the forming bloc-k wheel and the folding devices; Fig. 13 anenlarged detail plan view of a portion of the receptacle wheel and thetop folding devices; Fig. 14, an enlarged detail perspective view of aportion of one of the jaws P.

Similar letters and figures refer to similar parts throughout all theviews.

A represents the frame, which may be of any suitable form.

B and C represent horizontal wheels rigidly secured to vertical shafts aa resting in suitable hearings in the frame. The wheel B consists of aseries of spokes B radiating from the shaft 00 on the ends of which aresecured or are formed a series of open-ended receptacles D in which thewrappers, properly formed or shaped to receive the material to bepacked,

are deposited preparatory to being filled, and

the wheel G, which consists of the spokes O radiating from the shaftaandconnected with a rim 0 on the under side of which is secured or formedthe downwardly extending projection g carries a series of forming-blocksE, the construction and will be hereinafter described, corresponding innumber to the receptacles, around which the Wrapping material is foldedor bent to the desired shape preparatory to being deposited in thereceptacles.

The forming-block wheel, 0, stands or is arranged on its shaft above theplane of the receptacle Wheel, B,'a distance a little greater than theheight of the forming-blocks, and its rim overlaps said wheel, B, alittle more than the width of a forming block at the intersection of thewheels.-

The wheels are so operated as to move and come to rest simultaneouslyand the series of forming blocks and the series of receptacles are soarranged relative to each other as to cause the forming blocks toregister with the receptacles at the point of intersection of thewheels, so that the former may be forced down and into the latter at theproper time and the wrapper carried thereby, properly formed or shapedto receive the material to be packed, may be deposited in thereceptacles to be filled with the material and to have the tops foldedand gummed as hereinafter described.

F represents two notched or ratchet wheels secured to the upper ends ofthe shafts a a in line with each other and G a horizontal sliding bararranged at one side of said wheels, F, and supported in suitable guidesdepending from the cross beamsA' said bar being arrangement of which Iranged under the wheel 0.

.both slightly provided with two pivoted spring held pawls 1) arrangedand adapted to engage the notches c of the wheels F, and thus impartmotion simultaneously to said ratchet wheels and through the shafts aand a to the wheels B and O. The notches c correspond in number to theforming blocks and receptacles and are sunken in the edges of the wheelsand their rear walls are slightly curved so that the pawls may retaintheir hold therein at the extent of their throw and thus prevent thewheels slipping after the pawls have come to rest at the limit of theirmovement and so that, on the return movement of the pawls they may slipout of the notch. The rod G is operated by a cam wheel d secured to thedriving shaft II, said wheel having an eccentric groove formed in oneface in which a pin (Z' on the end of the rod G works so that eachrevolution of said shaft H causes a forward throw or movement of the rodand imparts a partial revolution in the same direction to the wheels Band G and brings the same into the proper positions for the varioussteps of forming the body of the wrapper, folding the ends, and fillingthe wrappers, and discharging the completed package.

The devices for attaching the wrapper to the forming block and forfolding and gumming the lower end of the same are shown in Figs. 1, 3,4, 5, 6, 7, 11 and 12.

In Figs. 1, 3, 4, 11, and 12 I represents a pair of jaws pivotallysecured at their rear ends to studs 6 secured to a fixed plate '1" ar-The jaws I are curved in the same general direction, and their free endsdiverge,standing apart at their front ends sufieiently to permit theentrance between them of the forming blocks, and near their rear endsthey are formed with off-sets h, Bent springs e having one end securedto apin orstud attached to plate a" and having their free ends bearingagainst the jaws I serve to hold the jaws normally closed or in theposition shown in Figs. 1 and 3. Immediately in front of the free endsof the jaws I two upright plates ffare rigidly secured to a smallplatform f which is secured to supports f projecting from one of thelongitudinal beams of the frame as shown in Figs. 3 and 12, one at eachside of the entrance to the jaws, between which plates the formingblocks pass as they enter between the jaws, said plates being soarranged that only suilicient space is left he- ;ween their contiguousedges for the passage )f the blocks. The wrapping material is zlamped orheld against the face of the formng block by a spring clamp consistingof a Ongue g (Figs.2 and 12)p1vo:tally supported hrough its shaft g inlugs g secured to the orward face of the downwardly projecting xtensiong of the wheel C, one end of said haft being formed square outside ofits bearig in the lugs, as at 9 and on this square 1d the free end of afiat spring g bears, the :her end of said spring being secured in anyshort extension Figs. 11 and 12.

desired manner to the inner face of said extension g, so as to hold thetongue in its set position, either horizontally up and out of contactwith the forming block or downwardly and against the forward face of theblock or the paper thereon. The tongue 9 is raised by hand and thewrapping material is inserted or fed to the machine in sheets of thedesired size in front of the spreading or free ends of the jaws I on theplatform f at the point designated by the arrow marked with the numeral2 in Fig. 1, and also as shown in Fig. 3, where a sheet of paper isshown clamped on the block and marked with the numeral 1 said wrapperbeing inserted edgewise and placed on the forward face of the formingblock E, so that its ends project beyond said block equally at each sidethereof in which position it is held by the tongue 9, which is turneddown thereon by hand at the moment the wrapper is inserted, and iscarried between the plates f and between the jaws I at the next movementof the wheel 0. As the wrapping material is carried between the platesfit is bent back on the forming block thereby at each side, thus formingthe front and two side walls of the body of the wrapper, and as theblock leaves or passes the upright plates and enters between the jaws I,forcing the same apart as it progresses therebetween, the side folds orwalls of the wrapper are held against the block by said jaws pressingthereagainst. As the wheel continues to move forward the forming blockpasses the offsets h and the jaws instantly close or spring together ortoward each other causing the offsets to press the ends of the wrappingmaterial inwardly thus forming the two last folds of the wrappingmaterial around the block and completing the body of the wrapper. One ofthe offsets closes slightly in advance of the other, owing to the factthat the forming blocks are moved in a circle, which causes the innerend of the block to pass the inner offset slightly in advance of theouter end, thus bending or folding one end of the wrapping materialbefore the other end, so that the latter may overlap the former. At thelower edges of the jaws I, adjacent the offsets h, I provide two thinhorizontal plates 2', one on each jaw and arranged opposite each otherand at a short distance from the offsets so as to leave a space to admitthe rear or third side of the bottom, which is subsequently folded byplate j, between it and the offset, which plates, when the jaws springinwardly, bend or fold the ends of the wrapping material in under thelower end of the forming block, th us forming two quarter folds of thebottom of the wrapper. he third fold for the bottom of the wrapper ismade by a thin folding plate 3' secured to the end of a short arm Jwhich swings in and out. Said plate being formed tapering orwedge-shaped forces the jaws apart as it enters between the s z" of saidjaws, as shown in In Fig. 4 the platej is shown 19 extending under thejaws as having forced the jaws apart and as. just passing the ofi'setsh. I

The arm J is loosely secured at one end to a vertical shaft J, having abearing in a cross beam J of the sub-frame a (Figs. 1, 3, 4, 5 and 12)provided with a crank arm is at its upper end, and to the latter isattached a connecting rod Z (Figs. 1 and 12) said rod being operated bya cam wheel m on the driving shaft H, through a pin Z on the end of therod which engages an eccentric groove in said cam. The short arm J turnsaxially in its supporting shaft J, the latter also turning axially inits bearing, and said arm J is provided with two short pins m m (seeFig. 5) which project from said arm at about right angles to each other.Above the arm J, as shown in Figs. 1, 3, 5, and 12, are arranged twoplates having oppositely inclining cam surfaces 4% and n against whichthe pins m m strike alternately during the inward and outward movementof the arm J. On the inward movement of arm J its pin m coming incontact with the cam surface n is turned down or from the vertical to ahorizontal position as shown in Fig. 5, thus turning said arm in itsbearing in shaft J and bringing the folding plate j from a downwardlyinclined position to a horizontal position in which position it iscarried inwardly to make the third fold of the bottom of the wrapper,and upon the outward movement or return of the arm J its pin m strikes aainst cam surface n and is deflected and causes the arm to turn in theopposite direction thus reversing the position of the plate j orreturning it to a downwardly inclining position in which position itstrikes against and is moved over and on the roller 0 of the gummer andthe paste is applied to it from contact therewith. The gumming device isarranged to one side and in position to permit of the contact therewithof the plate j, and it may be of any suitable kind, that shown, (seeFigs. 3, 4, 7 and 12,) being a box a in which are mounted any desirednumber of rollers a which extend into the paste and at one end of saidbox the roller 0 is mounted above the other rollers and in contact withthe end roller of the series of rollers a The box is supported bybrackets a projecting from a sub-frame a secured to and projecting fromthe main frame.

The fourth and last fold of the bottom of the wrapper is made by afolding plate 19 (Figs. 8, 4, 6, and 12) secured to a cross shaft I andwhich is adapted to be given a partial revolution as hereinafterdescribed. The shaft 19 has its bearings in projections 11 from theplate 1 as shown in said Figs. 3, 4 and 12. After the swinging folderjhas nearly completed its fold, the third, or has nearly reached thelimit of its inward movement and while still moving in under the blockthe folding plate 19 is turned quickly up bending the paper or otherwrap ping material to form the fourth and last fold for the bottom ofthe wrapper onto the lower surface of the folding plate j and is pressedtightly thereagainst during the further inward movement, which islimited, of the said plate j and thus, for alimited period, holding theupper surface or inner side of the fourth fold of the wrapper bottomfirmly against the paste covered surface of said plate j, said pastebeing thus wiped onto the fold by the inwardly moving plate j, drawal ofthe latter said paste covered side of the fold is left in contact withthe outer surface of the third fold, and the folding plate 19 drops backto its normal position, either through force of gravity, or by the useof a torsion spring arranged around its shaft p. The folding plate 19 isoperated by means of a chain 8 (Figs. 1, 3, 4, 6 and 12,) or othersuitable connection, between the crank arm is attached to the verticalshaft J and a correspondin g crank arm q attached to the shaft p of thefolding plate 19. In order to permit of the folding plate j movinginwardly nearly the full extent of its throw before the folding plate 19is brought into operation the connecting chain .9 is made sufficientlylong to remain slack during the greater part of the movement of saidplate j and the crank arm is is of a greater length than crank arm q, sothat instantly upon the tightening of the chain the folding plate 19 isbrought quickly up to make the last fold, bending the wrapping materialfirmly against the paste covered under surface of plate j.

The mechanism above described accomplishes the bending of the wrappingmaterial bodily around the forming block and the folding and gumming ofthe bottom end of the wrapper, and produces an open-topped wrapper readyto be filled, which is carried around by the wheel 0 to the point of itsintersection with wheel B with its bottom end in contact with a fixedplate '1" secured to the frame immediately under said wheel 0, saidplate beginning or extending from a point in rear of the shaft 19 of thefolding plate 19 about two-thirds the whole distance around the wheeland terminating at the point of intersection of the wheels where thewrappers are deposited in the receptacles D of wheel B, as indicated atT but said plate may terminate nearer the free ends of the jaws and anopening be formed therein at the point where the wrapper is to bedeposited in the receptacle wheel, if desired. Owing to thisconstruction and arrangement the folded bottom end of the wrapper isheld in close contact with the plate 1" and the bottom of the formingblock sufficiently long to enable the paste to dry hard enough to holdthe folds together so that when it arrives at the point whereit is to bedeposited in the receptacle wheel it will retain the shape given'it bythe folding plates and forming blocks! After the wrapper is deposited inthe receptacle D, by means which will be hereinafter described, onemovement of the wheel B and upon the withbrings the receptaclecontaining the wrapper under the filling apparatus. This consists of atube M, Figs. 1, 2, and 9, arranged in a socket bearings, supported froma cross beam A of the frame of the machine, by a depending bar orbracket A see Fig. 2, so as to move freely up and down therein, and inthe tube M a plunger N having a concave lower end or head 11 is insertedso as to have free Vertical movement therein. At the lower end of thetube M are hinged, as atj four platesi adapted to swing outwardly and tomeet at their lower edges or free ends when closed by the springs 24,which are secured to the sides of the tube M and bear against the outersides of the plates t. These plates taper on their edges toward theirlower ends so as to form, when closed, a tapering point for the tube. Atone side of the socket s an opening is formed over which is fitted andsecured the discharge end of a hopper 10 through which the material isfed to the interior of the tube M and under the plunger head '0 throughan opening in the side of said tube, as clearly shown in Fig. 9.

The operation of the feeding and packing device is as follows: After thedesired quantity of material is fed into the tube, said tube movesdownward, cutting oif the delivery of the material, and forces itspointed end into the open ended wrapper resting in its receptaclethereunder, said tube being so adjusted that its pointed end will reachnearly to the bottom of the wrapper before it comes to rest. The plungerN then descends forcing the material contained in the tube into thewrapper and at the same time expanding or forcing outwardly the lowerends of the plates t against the foursides of the wrapper, straighteningthe same and insuring the proper filling of the wrapper. The tube M isthen withdrawn from the wrapper, the plates 23 being thereby drawn outvertically therefrom, while the plunger N remains therein resting on topof the material pressingit down, and preventing it from being drawn outwith the tube or its end plates t. After the tube has been withdrawn theplunger rises to its normal position in readiness to be again operated.This fills the wrapper with the material and packs the same therein andthe next movement of the wheel brings the filled wrapper into positionfor folding and gumming its top. The devices for accomplishing this areshown at the bottom and to the right in Figs. 1 and 2, and in theenlarged detail views, Figs. 13 and 1 f.

The devices for folding and gumming the top are substantially similar tothose already described for folding and gumming the bottom, except thatinstead of the horizontal plates 2' which make the first folds for thebottom, I use swinging plates y to make the corresponding folds for thetop of the wrapper.

Referring to Figs. 1, 2, 13 and 14 of the drawings P represents springjaws, arranged in a manner similar to the jaws I, and secured to postsor studs projecting from a plate S,

faces to force apart the jaws and permit of the easy entrance of saidreceptacles therebetween. The jaws P are formed or provided with offsetsh, similar to the ofisets h of jaws I, in order to permit of thenecessary inward movement of the jaws to operate the swinging foldingplates 3 which make the first folds for the top of the wrapper. Theseplates, 3 are hinged or pivoted at one side edge to projections g whichare secured to the upper edges of the rear portion of the jaws P and atthe other side to projections g formed on the upper edges of the offsetsh as best shown in Fig. 14, said plates 1 being pivoted at a point aboutthe center of their lengths and having their lower ends formed orprovided with extensions of which are of greater-thickness than theplates, proper, and which act as counterbalances therefor, the front orinner sides of the extensions being curved or rounded off as indicatedin both solid and dotted lines, Fig. 14, at 1 so that the said frontsides of the extensions project beyond the plane of the front faces ofthe plates, proper, and as the receptacles pass the offsets they willstrike against said front sides of the extensions and force the latteroutwardly. As the receptacles wholly or bodily pass the offsets thespring jaws P immediately spring inwardly or toward each other and closeupon the receptacles within the offsets, thereby causing the extensionsg to be brought with considerable force againt the end walls of thereceptacles thus swinging the same outward and raising them to ahorizontal position and swinging the plates n quickly inward and downonto the wrapping material at the ends and bending the same inwardly anddown on the top of the material contained in the wrapper to make thefirst folds for the top of the wrapper. The jaws P are cut away, as aty, to permit of the plates being turned on their pivots, and after thereceptacles pass on the weight of the extensions 1 serves to return theplates to a vertical position in readiness to be operated to fold theends of the next wrapper. The last two folds of the top of the wrapperand the pasting or gumming of the same are made by a plate a secured toa horizontally swinging shaft 2 carried by and turning axially in avertical shaft .2 operated by a cam wheel 2 on the driving shaft Hthrough a rock lever L and a connecting rod 2 loosely attached to thelower end of said rock lever and to a crank arm 11 of shaft .2 and acrank arm I) secured to said shaft .2 is connected by a chain 5 to acrank arm b of a horizontal shaft b pivotally mounted in the end of aplate b to which shaft is secured a plate Z) for making the last of thefolds, the operation and construction of these parts being similar tothe parts for making the correthe bottom of thewrapper sponding folds ofIIO excepting that plate b turns down instead of up to make the folds,and a sub-frame b is arranged on the main frame to support the partssimilar to sub-frame a The gum ming device having a roller 0' isarranged adjacent the top folding mechanism, in position to be struck byplate 2, as shown in Figs. 1 and 13, and'cam plates n and a similar tocam plates n n similar to those shown in Fig. 6,are arranged under thehorizontal shaft 2', against which pins, similar to pins m m strike toturn the shaft and operate the plate in the proper manner to make thefold and apply the paste, the operation being in all respects, except asnoted,

similar to the operation of the corresponding parts of the devices whichfold and gum the bottom end of the wrapper. The wrapper thus filled andsealed at both ends forms a rectangular package which is carried aroundto the point of discharge from the machine by the receptacle wheel 13,during which movement the upper'end of the package is held in contactwith a fixed plate 12 secured in the frame above the receptacle wheel Band its bottom end rests on a fixed plate S arranged under said wheel,so that the sealed ends of the package are held firmly until they reachthe point of discharge and the paste is thus given ample time to hardenor dry and fix the end folds together.

The point of discharge for the packages is at the last station or pointof rest of the wheel B before reaching the point where the wrapper isdeposited therein at the intersection of the wheels and is indicated byan arrow marked with the numeral 3' in Fig. 1, at which point the plate11 terminates, and the under plate S is formed with an opening Z2 seeFig. 8, through which the package passes when forced out of thereceptacle. This is accomplished by a plunger rod T, Figs. 1 and 8slidably mounted in a guide or support T of the frame and operated byany suitable means, as may be also the plunger N, the feeding tube M,and the forming blocks E. I have shown a simple and efiectivearrangement of lovers or rock arms with a shaft for operating theseparts and will hereinafter describe the same.

The forming blocks E are secured to the lower ends of rods m whichextend through the rim of wheel 0 and have formed on or secured to theirupper ends cone shaped heads W said rods with the blocks thereon beingheld up by spiral springs 0 which surround them as shown in Figs. 2 and12.

The means which I show for operating the forming blocks, and theplungers, consists of a rock shaft V mounted in the upper part of theframe above the wheel 0 and operated from the driving shaft H by a rocklever d suitably pivoted to asupport d from the frame and connectedthrough a slot in its end with the pin of a crank arm a secured to saidshaft V and vibrated by a cam d on the driving shaft H which is formedwith an eccentric groove into which a pin on the lever 01 takes. A crankarm g secured to the rock shaft V, is connected through a slot in itsfree end to the upper end of a vertical rod 9 passing through tubularguides h secured in a cross beam A of the main frame, which carries acone shaped socket p at its lower end adapted to fit over the heads h ofthe rods m of the forming blocks when the crank arm 9 is depressed andthus force the forming block with the wrapper thereon down into thereceptacle which lies beneath the same in wheel B and upon the arm grising the spring 0 will throw or raise the forming block upwardlyleaving the wrapper in the receptacle. A crank arm f similarly securedto the rock shaft Vis connected through a slot at its free end to a pinon the upper end of a rod N which is loosely connected to the plunger Nand raises and lowers the same at the proper time, and another arm hsecured to the rock shaft and connected to the upper end of the plungerT through a short rod T (see Fig. 8) operates the latter to effect thedischarge of the filled and sealed packages. The feeding tube M isoperated directly from the driving shaft H by cam wheel Z thereon whichvibrates a rock arm k pivoted at one end to a bracket 10 and at itsother end to a lug 10 on the feeding tube, said rock arm k having a pin10 as shown in dotted lines Fig. 1, which engages an eccentric groove inthe cam wheel.

/ It is evident that many minor changes may be made in the constructionof the machine without departing from the spirit and scope of myinvention and I do not, therefore, desire to be limited to the exactconstruction of the, partsand arrangement of the same as hereindescribed. It is also obvious that the Wheels B and C may besimultaneouslyintermittently rotated in opposite directions, or towardeach other insteadof away from each other, and the same result obtained,by a mere transposition of the parts to correspond and the employment ofa sliding rod G and pawl 19 for each wheel instead of one rod carryingtwo pawls as hereinbefore described, said rods, in this event beingarranged at opposite sides of the ratchet wheels.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is
